Design of supply and exhaust ventilation system

Health and well-being, working capacity and mood depend largely on the air environment and microclimate in which a person works and lives. In modern world we are surrounded by bacteria, smog, dust and constant noise on the streets. In modern times, ventilation systems, which are supplemented by air conditioning systems, they play the role of a process aimed at maintaining a comfortable microclimate at work, production, at home and in public places.

Design of supply and exhaust ventilation consists of complex of works, including the estimation of required quantity, quality and equipment nomenclature. For exhaust and supply ventilation, system calculation aimed at achieving a balanced operation with the maintenance of basic parameters of air exchange, the development of necessary drawings, schemes, equipment list, as well as the rationale for choosing one or another technical solution.

[su_spoiler title=”Design of supply and exhaust ventilation system consists of the following stages:” style=”fancy”]

Design of general ventilation scheme
Calculation of heat input for ventilation design
Requirements for ventilation design
Technical and economical requirements for ventilation design
Working project of ventilation system

There are regulatory documents for heating, ventilation and conditioning systems. One of the main such documents is construction norms and regulations 2.04.05-91 (2000) “Heating, ventilation and conditioning” and SNiP, indicating the necessary type of the building. Consumption and temperature of supply air for ventilation is designed in accordance with mandatory annex to SNiP 2.04.05-91 (2000) where the certain method of calculation is indicated. For example, for designing of administrative buildings ventilation is necessary to take into account SNiP 2.09.04-87, part 4 “Heating, ventilation and conditioning of the air”.

Thus, from 3 main sources, such as:

Set of ventilation schemes known for this building
Regulatory documents (SNiP and other documents)
Specific customer’s requirements

– Principle scheme of premises ventilation and normative multiplicities are of air duct are deduced. Principle scheme of premises ventilation and normative multiplicities are of air duct are deduced.

External heat loads occur outside of the room. They can be either positive or negative.
Internal heat loads created by people and machinery. On the contrary, they are always positive.

It is necessary to take into account necessary points:

Sanitary requirements
Building and architectural requirements
Fire protection requirements
Operational requirements
System reliability
Economic requirements

[su_spoiler title=”Technical and ventilation requirements of ventilation design” style=”fancy”]

There are no exact calculations of ventilation system in feasibility study, but the following is noted:

Ventilation principles
What are main performance characteristics
What is approximate installation of ventilation equipment
Where is it supposed to locate the equipment
How much will this ventilation system cost

[/su_spoiler]

[su_spoiler title=”Working project of ventilation system” style=”fancy”]

Working project includes:

Equipment parts
Layout of ventilation equipment
Plans for air ducts and pipelines networks

Working draft of ventilation system is approved in matching organizations (HIS, fire inspection, etc.), if necessary, corrections are to be made.
